how 'default=saved' should work ?

[Frédéric Boiteux]

        Hello,

  I've recently updated my grub-legacy bootloader to Grub2 (using
  latest grub-pc from Debian Sid), and I can't have the 'default=saved'
  option working with Grub2 :-(

  I've put following definition in /etc/default/grub :

GRUB_DEFAULT=saved

and I get it in the beginning of my /boot/grub/grub.cfg :

...
### BEGIN /etc/grub.d/00_header ###
set default=saved
...

but I don't have anything in each menuentry telling to save choice :

menuentry "Debian GNU/Linux, with Linux 2.6.32-trunk-686" {
        insmod ext2
        set root=(hd0,8)
        search --no-floppy --fs-uuid --set 257cf3a6-a439-4bbd-9a71-e777eabe4a0e
        linux   /boot/vmlinuz-2.6.32-trunk-686 
root=UUID=257cf3a6-a439-4bbd-9a71-e777eabe4a0e ro  quiet
        initrd  /boot/initrd.img-2.6.32-trunk-686
}


and at every boot, I have the first choice hightlighted .

What does I miss ?
